To manage disks, go to Storage and click Disks on the top right of the screen to display the Storage Disks screen.
Select the disk on the list, then select Edit.
The Disks page lets users edit disks, perform manual tests, and view S.M.A.R.T. test results. Users may also delete obsolete data off an unused disk.
Performing Manual S.M.A.R.T. Testing Select the disk(s) you want to perform a S.M.A.R.T. test on and click Manual Test.
Disk Namespace Disk Commands Interactive Argument Editor (TUI) Get_Instance Command Get_Unused Command Query Command Resize Command Retaste Command Smart_Attributes Command Temperature Command Temperature_Agg Command Temperature_Alerts Command Temperatures Command Update Command Wipe Command Disk Namespace The disk namespace has 12 commands and is based on disk management functions found in the SCALE API and web UI. It provides access to disk management methods through the disk commands.
Disk Commands The following disk commands allow you to view and edit disk properties.
Disks Screen - Expanded Disk Batch Operations Bulk Edit Disks Manual S.M.A.R.T. Test Dialog S.M.A.R.T. Test Results if diskname Screen Wipe Disk Dialogs Edit Disk Screen The Disks screen displays a list of the physical drives (disks) installed in the system. The list includes the names, serial numbers, sizes, and pools for each system disk.
Use the Columns dropdown list to select options to customize disk the information displayed. Options are Select All, Serial (the disk serial number), Disk Size, Pool (where the disk is in use), Disk Type, Description, Model, Transfer Mode, Rotation Rate (RPM), HDD Standby, Adv.
Replacing a Failed Disk Taking a Disk Offline Restoring the Hot Spare Hard drives and solid-state drives (SSDs) have a finite lifetime and can fail unexpectedly. When a disk fails in a Stripe (RAID0) pool, you must recreate the entire pool and restore all data backups. We always recommend creating non-stripe storage pools that have disk redundancy.
To prevent further redundancy loss or eventual data loss, always replace a failed disk as soon as possible!
ZFS pool importing works for pools that are exported or disconnected from the current system, those created on another system, and for pools you reconnect after reinstalling or upgrading the TrueNAS system.
The import procedure only applies to disks with a ZFS storage pool. Do I need to do anything different with disks installed on a different system? expand When physically installing ZFS pool disks from another system, use the zpool export poolname command in the Linux command line or a web interface equivalent to export the pool on that system.
The disk wipe option deletes obsolete data from an unused disk.
Wipe is a destructive action and results in permanent data loss! Back up any critical data before wiping a disk. TrueNAS only shows the Wipe option for unused disks.
Ensure you have backed-up all data and are no longer using the disk. Triple check that you have selected the correct disk for the wipe. Recovering data from a wiped disk is usually impossible.
